-AUTOGRAPHIC CAMERA.

Specification of Letters Patent.

Patented Sept. 25, 1917.

Application filed April G, 1916. Serial Nb. 89,386.

To all whom t may concern.'

Be it known that I, ROY IViLMo'r, a citizen of the United States, residing at Larimore, in the county of Grand Forks and State of North Dakota, have invented cerftain new and useful Improvements in Autographic Cameras7 of which the following is a specification.

This invention has relation to an autographic device for film cameras, and the nature and objects thereofY will be readily apparent to those skilled in the art to which it appertains, in the light of the following explanation of the accompanying drawings, illustrationr what I now believe to bc the preA ferrcd embodiment, or mechanical expression, of my invention from among other forms and arrangements within the spirit of the invention and the scope of the appended claim.

,Howevelg an object of the invention is to provide means located in the autographic opening of a camera of the character described, for absolutely prccluding light from entering the camera through said' opening to fog or otherwise injure the sensitive film, while the desired inscription is being written on the film.

In addition to the foregoing my invention comprehcnds improvements in the details of construction and arrangement of parts to be hereinafter described and particularly pointed out in the appended claim.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference, throughout the several views in which they appear;

Figure 1, is a view in rear elevation of a portion of a camera illustrating the autographic opening and my invention applied thereto.

Fig. 2, is a longitudinal section through the rear portion of the camera.

Fig. 3, is an enlarged detail section illustrating the releasablc catch.

In autographic cameras as heretofore constructcd, there exists the possibility of light entering the opening, and of reflection from the interior surfaces of the camera, resulting in fogging of the sensitive film. This possibility icrcascs after the camera has been subjected to considerable usage and therefore impairs the usefulness thereof even when the autographic arrangement is not in use.

I propose therefore to obviate the disadvantages stated above by means disposable within the autographic opening to preclude entrance of light therein, in connection with the cover for said opening, which cover is in .closed position when the autographie device is not in use.

With reference to the drawings 1 indicates the removable back of a camera provided with an autographic opening 2, which is normally closed by a cover 3, having perforated ears -l disposa ile between ears 5 forming a part of the camera back, said ears being adapted to receive a pintle 6 thereby forming a hinged connection for said cover.

The spools 7 upon which the film is wound for the' purpose of extending the film across the light entrance of the camera and receiving the image, and for disposingsaid film in -close relation to the back of the camera. A. ledge 12 is provided for the film to rest upon while the writing is being transferred and to form a foundation so that sufficient force may be applied to the paper when writing.

One of the novel features of my invention isI a rectangular frame 13 disposed within the autographic opening and movable therein, and mounted upon the ends of flat spring members 14 secured at their other ends to the inner side of the camera back. An extension 15 is formed centrally upon the frame and is disposed in a recess 16 in the camera. back, said extension 15 being further provided with a button 17 extending through an opening 18 intersecting the recess 16 so as to expose the button at the back of the camera. An enlargement 19 is provided upon the inner side of one of the frame members for engagement with a lip 20 forming a part of the'cover and extending into the space of the rectangular frame 13, to retain the cover 3 closed against the tension of its spring.

In operation when it is desired to autograph the film after exposure, the button 17 is pressed, thereby moving the frame 13 toward the film backing against the tension of the spring members 14 and also resulting in the release of the cover 3. owing to the disengagement of the enlargement 19 and the coacting lip 20. The cover 3 is thrown back under the influence of a spring 23 surrounding the pintle 6 thereby exposing the autographic opening of the camera. Continued pressure upon the button 17 applies are located at opposite ends of the camera the frame 13 to the hacking paper, thereby pressing the paper to the film lat points defined by the contour of the frame. In this manner light entering the opening through the frame 13 cannot reach any portion of the film owing to the fact that the contact between the aper and the' film around the edges of the rame absolutely precludes such entrance. The paper exposed within the frame 13 may he written upon in the usual manner the cover 3 then "closed over the opening, and the slot closing button 17 released. The frame 13 is returned to former position underthe iniuence of vthe springs 14 resulting in rengagement between the enlargement 19 and the lip 20 whereby the cover is retained in closed position. For limiting the inward movement of the frame 13 the button 17 is longitudinally slotted at 21 for the rece tion of a pin 22 securedat either end to t e camera back.

Thus it will be seen'that I have provided an improvement in the autographic Vprin.

cple as applied to cameras by inclosing the area of the film to be inscribed so as to preclude entrance of light, and roviding a cover for closing the autograp ie opening when the camera is not in use.

While I vhave described and illustrated my invention with some degree of particularity, various ways of rea-constructing the apparatus, or the employing the principle thereof will oceur to those skilled in the mechanical arts, and I therefore reserve the right and privilege of changing the form of the details or otherwise altering the arrangement of parts without departing from the spirit of thc invention or the scope of the appended claim.

Hav-ing thus described my invention what I claim as new and desire to secure by Letters Patent is:-

In an autographie camera having an autographic opening, the combination of a. hingedly mounted closure for said opening, spring means for urging the closure to open position, a frame movable within the camera. behind the opening, resilient means for normally retainmg the same out of engagement with the film hacking: paper, means on the frame whereby it may be pressed against the paper, and coacting means on the frame and closure operating to retain the closure'in closed position, said eoaeting means being separable when the frame is moved to permit the closure to open.
